That's an authoring requirement, like pretty much everything to do with
element content models.
As in, if you have a <link> without itemprop but with rel inside <body>
your HTML validator will complain at you (and chances are your page will
end up with FOUC and whatnot, which is why this is not something the
spec makes valid).

Yes, and the spec requires that behavior. Note that
says nothing about where the <link> is located. You could stick it as a
child of the <html> (or even as the documentElement) and that algorithm
would still run.

The spec lists UA implementation requirements and authoring
requirements. Generally speaking, the UA requirements define processing
of all input, including input that is not valid per the authoring
